Field of the Invention
[0001] This invention generally relates to the art of electrical connection and distribution
systems and, particularly, to a raceway for housing electrical components such as
connectors or power blocks, circuitry and the like.
Background of the Invention
[0002] There are various applications or environments wherein structural raceways are used
to house electrical components and/or circuitry to hide the circuitry, to protect
the circuitry or for other purposes.
[0003] An example of such an environment is in space divider systems for dividing offices
or other interior regions into smaller work areas. Such systems normally include a
plurality of upright panels releasably joined together, and, in contemporary environments,
the panels are individually prewired, with electrical connectors or terminating power
blocks of adjacent panels being joined by flexible electrical components. Such systems
afford the user high flexibility in arranging and rearranging work areas to meet changing
work situations.
[0004] Delivery of necessary power and communications service to the various work areas
normally is accomplished in one of two methods. Each wall panel may be prewired or
a power supply and communications system may be installed in longitudinal recessed
areas of the panels or under the bases of the wall panels. In the latter systems,
normally a power and communication raceway structure normally extends longitudinally
of the panels to facilitate the extension of both electrical and communication circuitry
along the system in an efficient yet hidden and protected manner, still providing
utilization of the circuitry at selected locations.
[0005] Although known raceway systems have proven highly desirable and have met with success,
there nevertheless is continued attempts to improve the manufacture, usability, flexibility,
dependability and convenience of such systems, particularly in en- deavors to incorporate
the power and communications structural raceway as an integrally associated component
of panel divider systems. Accordingly, this invention relates to improvements in raceway
structures of the character described.
Summary of the Invention
[0006] An object, therefore, of the invention is to provide a new and improved raceway structure
for housing electrical components.
[0007] In the exemplary embodiment of the invention, a pair of elongated raceway sections
are provided such that, when in longitudinal juxtaposition, the sections define a
generally hollow closed structure for concealing and protecting the electrical components.
Hinge means are connected between adjacent longitudinal sides of the raceway sections
whereby the sections can be moved between open and closed positions. Complementary
interengaging latch means are provided on the opposite longitudinal sides of the raceway
sections to hold the sections in the closed position.
[0008] As disclosed herein, the raceway sections are unitary plastic components and the
complementary interengaging latch means are formed unitary with the raceway sections.
The latch means include hooks for snapping into locking engagement.
[0009] The hinge means are provided in the form of a web extending lengthwise of the raceway
sections. The sections have sockets longitudinally thereof, and the web has enlarged
portions for positioning in the sockets.
[0010] In the preferred embodiment of the invention, the raceway sections are generally
U-shaped in cross-section with each section having two leg portions joined at proximal
ends by a bight portion. The hinge means and the complementary interengaging latch
means are provided at the distal ends of the leg portions of the U-shaped sections.
[0011] It is contemplated that the raceway sections can be extruded of dielectric material,
such as plastic or the like. Therefore, the raceway sections simply are cut to desired
lengths, in pairs, to provide a closed raceway of that length when the sections are
interengaged.
[0012] Other objects, features and advantages of the invention will be apparent from the
following detailed description taken in connection with the accompanying drawings.

Detailed Description of the Preferred Embodiment
[0014] Referring to the drawings in greater detail, and first to Figure 1, the invention
is incorporated in a raceway, generally designated 10, which forms a component of
a power and communication supply system, generally designated 12, which may be used
in conjunction with a modular wall panel system. For instance, supply system 12 may
be provided in a bottom recessed area along the bottom edge of a single wall panel
of the modular wall panel system.
[0015] Power and communications supply system 12 includes an electrical connector or power
block, generally designated 14, within one open end 16 of raceway 10. A flexible conduit
18 projects outwardly from the opposite end of raceway 10, and another electrical
connector, generally designated 20, is electrically coupled to the power and communication
wires or lines within flexible conduit 18. As an example, connector 20 may comprise
a plug connector and connector 14 may comprise a receptacle connector. Therefore,
plug connector 20 can connected to a receptacle connector 14 of another power and
communications supply system 12 in an adjacent wall panel of the modular wall panel
system. Of course, it must be understood that supply system 12 is but an example of
the utility of raceway 10 which incorporates the concepts of the invention.
[0016] For instance, raceway 10 may interengage with other components such as mounting brackets
22 to facilitate mounting the raceway within or along the bottom of a wall panel.
In addition, raceway 10 may include side apertures 24 within which are mounted conventional
receptacle plates 26. It can be seen that each receptacle plate 26 has a pair of "three-
prong" arrays of holes for receiving conventional grounded electrical plugs. Appropriate
terminal contacts are provided within raceway 10 in communication with the holes to
terminate the conventional grounded plugs to electrical or communications circuitry
within the raceway and coupled between connectors or power blocks 14 and 20.
[0017] Referring to Figure 2 in conjunction with Figure 1, the invention contemplates that
raceway 10 be fabricated of a pair of elongated generally U-shaped sections, generally
designated 30 and 32. U-shaped raceway section 30 includes two leg portions 30a and
30b joined by a bight portion 30c. Likewise, U-shaped raceway section 32 includes
two leg portions 32a and 32b joined by a bight portion 32c. Raceway sections 30 and
32 are designed such that, when in longitudinal juxtaposition, the raceway sections
define a generally hollow closed structure for concealing and protecting the electrical
components therewithin, as seen in Figures 1 and 2.
[0018] Generally, hinge means 34 are interconnected between adjacent longitudinal sides
(i.e., legs 30b and 32b) of the raceway sections whereby the sections are movable
about the hinge means between an open position (Figs. 2 and 3) and a closed position
(Figs. 1 and 4). More particularly, hinge means 34 is provided in the form of a web
extending lengthwise of the raceway sections. The sections have socket means in the
form of channels 36 formed in the outside surfaces of legs 30b and 32b. The web has
enlarged side edges 38 which are disposed in channels 36 to retain the web in position.
The web is fabricated of flexible material so that sections 30 and 32 can pivot from
their open position as shown in Figure 3, in the direction of dotted arrowed line
40 to their closed position as shown in Figure 4.
[0019] Generally, raceway sections 30 and 32 include complementary interengaging latch means
on the longitudinal sides thereof opposite hinge means 34 (i.e., on legs 30a and 32a)
to hold the raceway sections in their closed position. More particularly, as seen
in Figures 2-4, leg 30a of raceway section 30 is provided with a hook 42 on the outside
thereof, and leg 32a of raceway section 32 is provided with a hook receiver or projection
44 on the outside thereof. Therefore, when the raceway sections are moved or pivoted
about hinge means 34, such as indicated by dotted arrowed line 40 in Figure 3, hook
42 will snap behind hook projection 44 as shown in Figure 4, thereby holding or locking
the sections in their closed position surrounding, concealing and protecting the electrical
components therein, such as receptacle connector 14.
[0020] The raceway sections may be provided with other interior or exterior features commensurate
with the usage of the raceway. For instance, hooks 46 are provided on the outside
of legs 30a and 32a of raceway sections 30 and 32, respectively. As seen in Figure
4, the hooks point outwardly in opposite directions. As seen in Figure 1, the hooks
may be used for snapping lips 48 of mounting brackets 22 onto the top of the raceway
to eliminate extraneous mounting hardware.
[0021] Reviewing the above description, raceway sections 30 and 32 can be fabricated individually
and then joined by the hinge means provided by web 34 as shown in Figure 2 wherein
the sections are in their completely open condition. The electrical components which
are to be mounted within the raceway, such as electrically connector 14, power wires,
communication cables and the like then are positioned within one of the raceway sections,
such as section 32 shown in Figure 3. The other raceway section, such as section 30,
then is pivoted to the closed position as shown in Figure 4, whereupon hook 42 snaps
into engagement over hook projection 44. The electrical components now are completely
concealed and protected within the raceway which has been provided by only two pivotally
connected parts.
[0022] Although raceway sections 30 and 32 can be fabricated by molding techniques, it is
contemplated that the sections be extruded so that they can be cut in any given lengths
to provide a raceway 10 of any length for a variety of desired applications.
[0023] It will be understood that the invention may be embodied in other specific forms
without departing from the spirit or central characteristics thereof. The present
examples and embodiments, therefore, are to be considered in all respects as illustrative
and not restrictive, and the invention is not to be limited to the details given herein.
